That happens, you can try a BIOS update, and also make sure your motherboard CMOS settings specify the port for serial0, and match port 0x3f8-0x3ff irq 4, and aren't set to auto. You can also try changing the setting for plug-and-play OS to off, (or on, if it was off before) You can ignore the message: "configured irq 4 not in bitmap of probed irqs 0" as long as your serial port actually responds. A lot of motherboards will emit this message but the serial port still works. Unfortunately it looks like yours isn't one of these due to the "not responding" error message. Worst case, disble the motherboard serial ports and buy a pci serial port card. This seems to happen a lot on systems that use pci-express, probably because they are tying the serial port hardware to the pci bus rather than the isa bus.
